        본 연구는 한국어가 인도네시아어로 번역되었을 때 나타난 결속구조 전환을 연구하는데 목적이 있다. 번역과 결속구조는 서로 긴밀하게 연 결되어 있다. 번역 과정에서 결속구조를 적절하게 해석하고 전달하는 것은 번역의 일관성과 의미 전달에 영향을 미치기 때문이다. 결속 구조 를 분석하기 위해 원문과 번역문에서 100문장을 추출한 후 보그랑데와 드레슬러(Beaugrande & Dresseler, 2008)의 결속구조 모델을 사용하 여 한국어와 인도네시아어의 결속구조를 분석했다. 분석 결과 한국어와 인도네시아어 번역문에서 대용형, 접속 표현, 회기법 및 부분 회기법, 환언, 생략법의 순서로 결속구조가 전환되었음을 확인하였다. 이 연구 내용이 번역 교육의 예시로 활용하거나 번역자들의 실무에 도움이 되 기를 기대해 본다.

        Peri-implantitis (PI) is bacteria-induced inflammatory condition which affects the alveolar bone and soft tissue around implants and may result in the loss of supporting bone. Attenuation of the P. gingivalis lipopolysaccharide (LPS)-induced inflammatory response can be a new therapeutic approach in the treatment of PI. This study was conducted to evaluate the anti-inflammatory effect of 635-nm light-emitting diode (LED) irradiation over MG63 osteoblast-like cell. Scratch was made on MG63 cells with or without LPS, then 635-nm irradiated. The expression of the cyclooxygenase-2 (COX-2) proteins was evaluated with western blot. The production of the prostaglandin E2 (PGE2) and expression of the receptor activator of nuclear factor kappa-B ligand (RANKL) and osteoprotegerin (OPG) was measured with enzyme-linked immunoassay, and the cytokine profile was evaluated with the human inflammation antibody array. Wound closure effect presented in the cells treated with LPS was observed more significantly in the cells with 635-nm irradiation than the cells without irradiation. The 635-nm irradiaiton reduced LPS-induced expression of the COX-2 and production of the PGE2. Also, 635-nm irradiation affect the expression of RANKL, OPG, and proinflammatory cytokines. These results indicate that 635-nm irradiation could reduce the alveolar bone resorption induced by LPS stimulation through the inhibition of COX-2 expression and PGE2 production, the suppression of proinflammatory cytokine, and the modulation of RANKL/OPG balance in MG63 cells.

        Topoisomerases are essential enzymes involved in all processes of DNA metabolism, and their inhibitors have been identified as potential anti-cancer agents. The present study examined the effect of linoelaidic acid (C18 polyunsaturated fatty) compounds derived from Gardenia jasminoids Ellis extract on the activity of eukaryotic topoisomerases inhibition. The present study identified linoelaidic acid compounds using open column fraction, HPLC, NMR and LC/MS which have effects on cell death in oral cancer cell line, FaDu, but not in immortalized normal cell line, HaCaT. Subsequent studies revealed linoelaidic acid-induced autophagy through LC3 activation. Finally, its inhibition of topoisomerase I and selectively induction of oral cancer cell death possibly implies that linoelaidic acid can be a role as potenial agents in the prevention and therapy of oral cancer.

        Ultraviolet (UV) light emitting diodes (LEDs) were grown on a patterned n-type GaN substrate (PNS) with 200 nm silicon-di-oxide (SiO2) nano pattern diameter to improve the light output efficiency of the diodes. Wet etched self assembled indium tin oxide (ITO) nano clusters serve as a dry etching mask for converting the SiO2 layer grown on the n-GaN template into SiO2 nano patterns by inductively coupled plasma etching. PNS is obtained by n-GaN regrowth on the SiO2 nano patterns and UV-LEDs were fabricated using PNS as a template. Two UV-LEDs, a reference LED without PNS and a 200 nm PNS UV-LEDs were fabricated. Scanning Electron microscopy (SEM), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), Photoluminescence (PL) and Light output intensity- Input current- Voltage (L-I-V) characteristics were used to evaluate the ITO-SiO2 nanopattern surface morphology, threading dislocation propagation, PNS crystalline property, PNS optical property and UVLED device performance respectively. The light out put intensity was enhanced by 1.6times@100mA for the LED grown on PNS compared to the reference LED with out PNS.

        본 연구에서는 직접 제작된 전도유체(electrorheological fluid)용 수직진동 rhemeter 기기상의 구조 해석 및 실험을 실시하였다. 수직진동 rheomether는 간단하게 제작이 가능하고, 고전압 발생장치를 연결하므로 전동유체의 점탄성 특성을 비교적 쉽게 측정할 수 있다. Rheometer의 구조적 변수와 측정된 힘, 변형 등을 이용하여 복소 점도(complex viscosity), 복소 전단 변형률(complex shear modulus), loss tangent 등의 선형 점탄성 물질 함수를 직접 계산할 수 있으며, corn starch를 polybutene/kerosene에 분산시킨 전동유체를 이용하여 전기장하의 점탄성을 측정하였다.
